double pitch

Black Ace Dual Pitch Roller Chain Sprockets are produced with the highest integrity. You will realize value, as these sprockets are flame-cut and machined with the best precision available on the market.

ANSI Standard Torch Profiles
A – B – C Hub Types
A Type (no hub) typically found in weld-on applications.
B Type (hub on one side) used in applications where clearance width is narrow. Less expensive than C Type.
C Type (hub on both sides) found in applications where B Type isn’t wide enough to withstand torques made by drive.
Split Style Building – Once you use a Split Sprocket, you may never want to use a setscrew mount design again. Removal or installation is a breeze. Can be used in practically all applications. Another advantage to Dark Ace’s split sprockets is definitely that the shaft/keyway protection is much tighter than a typical setscrew mount.
Hardening Available – Flame hardening of sprockets can be available as an option.
